Design of key technologies and methods Objectoriented programming technology Method of objectoriented programming is a kind of support software reuse and modular design method of practical programming, its basic idea is to encapsulate and scalability. Packaging to bring software modularity, security, and so on, because there is no data coupling, objects with no action taken as a result of boundary effects, therefore, easier to maintain and modify [. Scalability to leave system interfaces for easy integration with other systems, this system to work with the library, personnel management system management system, scientific management system, the Institute of financial management systems, Office OA system integration, people of the smooth realization of data export. System security technology Information security system construction of the first issue, of coursechoosing system key information (such as student achievement, student information, and so on) safety is essential, must be developed 濟(jì)南大學(xué)畢業(yè)設(shè)計(jì) 外文資料翻譯 5 at the design stage of the system construction of reliable security policy. This system from work traffic, server security, database management systems, systems, procedures, puter virus prevention and cure of the five regard provide security: (1) work munications: virtual local area work (VI, AN) services and firewall technologies. Your WEB server and database server system on College campus virtual sub, only allow internal users to access, shielded external user access. For work protocol for qualifying, cute as h, p Protocol allows you to access, such as FrP, TeNet Protocol implementation. (2) Server security. (3) the database account permissions and database, database view, account operations record operating information, concurrency control, trigger actions, such as time tracking, in addition, enables automatic data backup data, and so on. (4) system. a． Designed to dynamically set the user information in your application, access information, illegal may be effective in preventing the program from the system the client logs on to the system, and b. Application security control for database operations, will not cause half of the data submitted, or submitted error。 c. Data encryption technology, the system user (such as students, teachers, and so on) registered passwords are encrypted to eliminate user Session such as technology gets the password. (5) puter virus prevention: install legitimate antivirus on the server side With antivirus and firewall software, ensure that the functioning of the system. Database optimization techniques. (1) SQL statement optimization: SQL statement into the same purpose to be poor performance the performance of SQL statements. Using artificial intelligence, automatically overriding SQL statements, so as to find the best performance of an equivalent SQL statement. (2)
